Anybody noticed that google.co.uk has changed when you do a search?
A search for hello
EDIT; Only on firefox...
No, it is fine for me, although it has never really done anything like that for me anyways, it could always be a problem with how firefox is rendering it for you, did you update it to the new version?
Strange it's 'normal' here....
It's not a rendering problem. Google is just experimenting with the new design (which is why not everyone and at every time can see it). There was a story last year reporting people seeing that exact design shown on that screenshot by Andrew and saying that Google is experimenting with it in order to bring it as new design at some point.
